In Switzerland April 15, 1942 Claims. (Cl. 1Z0-24) Roll blottershitherto produced generally consist of a rocker to which a pad ofblotting-paper strips is attached, the ends of the strips being heid lnplace by a ilat clip. The parts of the blotting-paper strips lying atthe center of the rocker are subjected to particularly heavy use forblotting purposes and are thus prematurely used up, while the parts oneither side of the center are not fully utilized. The insertion of thestrips also causes certain diiculties, and the same is true of theremoval of a used strip.

The object of the present invention is a roll blotter. According to theinvention, a movable strip of blotting-paper is attached to the rockerand can be moved by hand with the aid of adjusting mechanism.

In the enclosed drawing the object of the invention is represented inone possible variation by way of example. The drawing shows:

Fig. 1 a vertical cross sectional view,

Fig. 2 a top view, with the covering plate partly removed,

Fig. 3 a front View.

I is the hollow wooden rocker, with curved undersection 2 and side walls3. To the under-side of the covering plate 4 are attached pegs 5, whichengage spring clips 6, the latter being affixed to the side Walls 3.Spring pegs 5 and spring clips B hold the removable covering plate 4firmly in the position shown.

1 is a revolving handle situated on top of the covering plate andequipped with a female thread socket 8 into which is screwed thethreaded upper section lof revolving bolt II. Bolt Il passes throughopening I2 in the covering plate and also through cross-piece I3, whichconnects the two side walls 3, and its lower end enters loosely intoblock I4, which is affixed to the inner side of the under-section of therocker. The middle section of the bolt is provided with a worm I5 whichengages cog-wheel It, the latter turning on spindle or shaft I1. On thisshaft is also a transport cog-wheel I9, the teeth of which engagecog-wheel 20, which is rigidly fixed on spindle 2l of receiving roll 22.The movable blotting-paper strip 23 .is wound upon receiving roll 22 asroll 23', and passes around the outside of rocker under-section 2. 24 isa paying-out roll, on which the movable blotting-paper strip 23 isrewound as roll 23". 25 is the spindle of paying-out roll 24. Theunder-section is provided at its ends, near to covering plate 4, withapertures 2S, and next to these are placed thev guide rolls 21 whichrevolve on spindles 2B.

If handlel 'I is turned in a clockwise direction,

revolving bolt Il and Worm I5A also turns. The latter turns cog-wheel I6and, by means of shaft I1 and-cogs I9 and .20, receiving roll 22 isturned in a counterclockwise,direction (Fig. l), so that the movableblotting-paper strip 23 is wound up and moved along on rockerundersection 2, a corresponding length of the blot- `ting-paper stripbeing wound off paying-out roll is turned in an antifrom the thread-2li. If, however, handle I clockwise direction, it unscrews ed uppersection l0 of bolt II, and covering plate 4 can be removed, the insideof the rocker thus being made accessible.

Paying-out roll 24 can be provided with a cogwheel in the same way asreceiving roll 22, so that the two can be interchanged and both sides ofthe blotting-paper strip can thus be fully utilized for blottingpurposes. The moving of 'the blotting-paper strip along theunder-section 2 of the rocker is effected quickly and easily by theturning of handle 'I. i

The rocker can obviously also be `manufactured in metal or articalmaterial. The essential requirement is that handle 1 of the rockershould serve at the same time to move the blottingpaper strip.

It will be obvious to those skilled in the art that various changes maybe made in thisv invention Without departing from the spirit thereof,-and the invention is not limited towhat is shown in the drawing anddescribed in the speciflcation, but only as indicated in the appendedclaims'.

I claim:

1. In a blotter of the character described, a hollow rocker, a blottingpaper strip underlying the rocker, a pair of rolls journaled in thehollow rocker upon which the ends of the strip are wound, a cover platefor the rocker, mechanism within the hollow rocker to effect movement ofthe strip over the rocker when transferred from one roll to the otherroll, including a rotary shaft in the rocker projecting upwardly throughthe cover plate, a handle attached to the upper end of the shaft and aworm gear drive between said shaft and one of said rolls.

2. A blotter as set forth in claim 1, wherein a cross piecel at theupper end of the rockerghas the shaft journaled therethrough and abearing block on the bottom of the hollow rocker into which the lowerend of the shaft is seated.

3. A blotter as set forth in claim 1, wherein pegs depend from the coverplate and spring clips are carried by the rocker to receive the pegs andretain the cover in position.

4. In a blotter of the Character described, a hollow rocker comprisingan arcuate bottom Wall, Vertical side walls and a removable top wall, aknob handle above the top wall, a blotting paper strip underlying therocker with the vends thereof extending into the rocker body, a rollwithin the rocker body adjacent each end thereof upon which the adjacentends of the blotting paper strip are Wound, -a gear trainwithin therocker body operatively engaged with one'of said rolls for the windingof the blotting paper strip thereon, said gear train including a shaftextending upwardly through thecover and an operating knob secured to theprojecting end of the shaft.

5. A blotter as set forth in claim 4, wherein the shaft is rotatable andthe gear train includes a worm Wheel meshing with a worm on the shaf t.
